Function cp::SizeOfNext(sequentialResource, scheduledActivity, lastValue, absentValue)

cp::SizeOfNext

The function cp::SizeOfNext refers to the size of the next activity in a sequence of activities. A size is an integer in the range \(\{0..card(\texttt{problem schedule domain})-1\}\). For a resource \(r\), an activity \(a\), sizes \(l\) and \(d\), the function cp::SizeOfNext(r,a,l,d) returns

  • \(d\) if \(a\) is absent,

  • \(l\) if \(a\) is present and scheduled as the last activity on \(r\), and

  • \(n\texttt{.size}\) if \(a\) is present and not scheduled as the last activity on \(r\), and \(n\) is the next activity of \(a\) scheduled on \(r\).
